Production
KHN45JU heat-resistant alloy is melted in open electric furnaces. Manufacturer KHN45JU wire, round, rod normalized GOST 5632−72, TU 14−1-2396−78, 14−1-2075−87, 14−1-941−74, 14−1-4082−86. The amount of Nickel in the alloy is 44−46%, iron 30,825 — 38,01%, chromium 15 — 17%. As additives are used: 2,9−3,9% Al, sulfur and silicon (less than 1% of each compound), up to 0.02% Mn, up to 0.025% P, not more than 0.03% of Se, up to 0.1% Ba.

Usually the circle is made of alloy steel with a length of 1−6 meters. Precision manufacturing is marked by the letters A, B and C, which means high, elevated and normal precision. Round without heat treatment is not labeled, thermally processed is denoted by T, full hard (subjected to rolling several times) it is marked by — N. The length can be dimensional, random or dimensional.

Treatment
Rashkovka of products produced in the thermal interval of 1180 — 850 °C. the recommended temperature of quenching in water or air up to 1200 °C. the Rod is quenched at 1050−1150°C in air. The alloy is easily welded, the welding can be performed in any way. For manual arc welding using electrodes OzL-35, OzL-25.
Application
KHN45JU wire rod used for the manufacture of furnace conveyor belts, the rollers in the slot furnace of a fast firing ceramic tiles, flat household ceramics and some other ceramic products. They can also be found in manufacturing parts of burners. The heat resistance allows details operate for a long time at temperatures up to 1300 °C. Range are used as blanks for the manufacture of the area, beams, profile special purpose, which are used in industrial construction. In the engineering of such a circle produces tappets, axles, bushings, etc. details. Wire is used for different fasteners, the manufacture of the springs. Wire is also produced parts of household appliances, electrodes for welding, reinforcement.
